A luminous point object is moving along the principal axis of a concave mirror of focal length 12
\( \mathrm{P} \)
\( \mathrm{cm} \) towards it. When its distance from the mirror is
W
\( 20 \mathrm{~cm} \) its velocity is \( 4 \mathrm{~cm} / \mathrm{s} \). The velocity of the image in \( \mathrm{cm} / \mathrm{s} \) at that instant is
(1) 6 , towards the mirror
(2) 6, away from the mirror
(3) 9, away from the mirror
(4) 9 , towards the mirror
